A-i.rotatable -heel section 26'; of circular outline-, contacts with;the elowerfsidemoff .the bodyf I6; and@ the; fperiplieral :edge-iI2:1aofxsaidilieek,sectiomzE; ush with the rear edge I9 of thezebodyelu.Both-e this rotatively adjustable heel section 26 and the body IB are ofconcavo-convex form before application of the heel to a shoe, as will beclear from Figs. 5 and 7, to insure tighter contact at the edges whendrawn into hat form. The upper side of the section 26 is provided withan integral boss 28 shaped for snug reception in the opening 2| of thebody I6, said boss being of a height to contact with the lower side ofthe leather heel 24, as seen in Fig. 4. The section 26 is formed with acentral socket 29 which opens through the lower side of said section,and is formed also with a central opening 30 which extends from saidsocket 29 to the upper side of the boss 23. An attaching screw 3|extends through the opening 30 and is of a length to be threaded tightlyinto the leather heel 24 as seen in Fig. 4.

In addition to securing the rotatively adjustable heel section 23 b-ymeans of the screw 3|, it is preferably cemented also to the body i6.The upper side of section 26, however, is provided with a plurality ofradial surfaces 32 which are so smooth that the rubber cement or othercement used, will not adhere to them. Such smooth areas 32 are obtainedby highly polishing the portions of the mold which form them. Theintervening areas 33 are made quite rough and are preferably raisedsomewhat from the surfaces 32, providing shallow grooves 34 in the heelsection 26. These grooves permit the insertion of a screw driver or thelike between the section 26 and the body I3 to pry said section offafter removal of the screw 3|, when said section is to be turned toanother position after wear, or is to be thrown away and replaced with anew section. The rubber cement will adhere to rough areas 33 and to thelower side of the body I6 which does not have the very smooth orpolished surface of the areas 32, and hence the cement will effectivelyhold the edges of parts I6 and 26 together.

A plug 33 normally iills the socket 29 below the head of the screw 3|and prevents dirt from accumulating in said socket. This plug is formedwith a small central bore 33, and one or more pull cords 3'! is/areanchored to said plug at the upper end of said bore, as seen at 38 inFig. 4. In the present disclosure, there are two of these pull cordsformed from a single thread folded upon itself as shown at 30. Normally,these pull cords are crammed tightly into the bore 35 as indicated inFig. 4, although the cramming is accomplished much more tightly thanshown in said view. When the plug 35 is to be removed, the pull cordsare picked from the lower end of the .bore 33 and are then pulledoutwardly as seen in 8, in which position, they may be readily used toextract said plug 35 from the socket 29. The plug is molded from rubberor the like and has anti-slipping fabric molded therein as indicated at40.

Preferably the body i'o, the rotatively adjustable heel section 2G, andthe plug 35, are all formed from rubber or some other resilient orcushioning composition but the body AIii maybe made of leather. Theentire structure may be expeditiously manufactured and profitably soldat a, reasonable price, and whenever the user' wears the edge of thesection 26 sufficiently to require adjustment of said section, he mayreadily remove it himself, turn it to another of its four positions whenthe boss is square, and refasten it in place. When this section hasbecome so worn as to be of no further service, it may be thrown away anda, new one purchased at small cost, and applied.

In the form of construction shown in Figs. 9 to 15, the body |6a isprovided on its lower side with lugs 20a shaped and arranged differentlyfrom the lugs 20 above described, and if desired some or all of theselugs may be detachably mounted. The upper portion of the body |60. isformed with a rib 25a corresponding to the rib 25, and a rotatable heelsection 26a is disposed against the lower side of said body, therelation of this section 26a with the rear end of the body |6a, beingthe same as that existing between the elements |6 and 26 abovedescribed. Moreover, the section 25a is secured in place both by acentral screw Sla and by means of cement, but the entire area of theupper side of said section may be cemented to the body lea. The section26a is formed with a central upstanding boss 28a receivable in anopening 2|a in the body |6a, and the lower side of said section 26a isformed with a socket 29a normally receiving a plug 35a which may beconsidered as identical with the plug 35.. Both the body |0a and therotatively adjustable section 26a are of concavo-convex form as shown inFigs. 13 and 15, before application of the improved heel to the leatherheel, for tighter contact around the edges when drawn into fiat formduring attachment.

From the foregoing, taken in connection with the accompanying drawings,it will be seen that novel and advantageous provision has been made forcarrying out the objects of the invention, and while preferences havebeen disclosed, attention is again invited to the possibility of makingvariations within the scope of the invention as claimed. For instance,itis not essential to provide the plug 35 or 35a with a pull cord, forit may be removed with the aid of any suitable instrument.

I claim:

A shoe heel comprising a body for attachment to a leather heel, arotatively adjustable heel section contacting with the lower side ofsaid body, and a screw extending centrally through said rotativelyadjustable heel section for detachably mounting the latter, the upperside of said rotatively adjustable heel section having smooth radialareas to which cement will not adhere tenaciously, the remaining upperareas of said rotatively adjustable heel section and the areas of saidbody in contact with 'said remaining upper areas being relatively roughto permit cement to readily adhere thereto, whereby if said rotativelyadjustable heel section be cemented to said body, it will possess radialareas not cemented to said body, to facilitate insertion of a tool forprying off said heel section when desired.
